New Delhi, Mar 17: The serviceability rate of multi-role fighter aircraft Sukhoi is likely to improve to 75 per cent by this year end from the current level of 56-57 per cent, Defence Minister Manohar Parrikar said on Tuesday.
"We have been trying to improve the serviceability of Sukhois. It has improved by seven per cent in last 8-9 months to reach to 56-57 per cent," he said in Rajya Sabha, exuding hope that it would go up to 75 per cent by the year end.
A total of 35 incidents of engine failures in air or other engine-related problems have occurred between January, 2013 and December last year.

"25 new engines with modified technology have been procured from Russia," he said.
Replying to another question, Parrikar said two new ordnance factories at Nalanda in Bihar and Korwa in Uttar Pradesh were being set up and a total investment of Rs 1,216 crore has already been made on the two projects.
